AERZEN Positive Displacement Blowers with pre-inlet cooling are made for moving air, neutral, or aggressive gases in industrial high-vacuum applications. Oil-free operation, vertical flow, and a choice of direct coupling or V-belt drive support continuous use without overheating. Eleven sizes cover a wide range of flow rates and vacuum levels.

  • Oil-free blowers for air, neutral, and aggressive gases in high-vacuum settings

  • Handles volume flows from 147,15 to 35,904,6 CFM and vacuum from 0.145 to 4.35 psi

  • Pre-inlet cooling reduces compression discharge temperature

  • Sealed vacuum-tight conveying chamber with double radial shaft seals

  • Continuous operation without overheating

  • Largest series worldwide with 11 size options

  • No need for extra controllers or valves during installation or operation
